Definitions

  • This invention concerns an apparatus for joining thermoplastic materials by the friction welding technique and more specifically relates to an apparatus for friction welding a reinforcing plate to the inner surfaces of oppositely disposed legs of a generally U-shaped workpiece.
  • the generally U-shaped channel comprises an automobile bumper and the plate is a reinforcing plate to strengthen the bumper to improve its impact strength.
  • a first workpiece to be welded is disposed in a fixture and held stationary.
  • a second workpiece to be joined to the stationary workpiece is urged into intimate contact with the mating surface of the stationary workpiece.
  • the two workpieces are caused to undergo relative linear reciprocating motion in the plane of the abutting mating surfaces.
  • the parts are urged together under the influence of a force applied in a direction normal to the plane of the mating surface.
  • the described method is known and is used, for example, to weld a cover over a U-shaped channel.
  • the workpieces are also placed in intimate contact and the parts undergo relative linear reciprocating motion.
  • the force urging the workpiece into intimate contact is applied in a direction normal to the direction of motion, but in the plane of the mating surface.
  • a stiffening plate is welded within the U-shaped channel as contrasted with welding the plate as a cover over the channel.
  • flexible force applying means are used to urge the workpieces into intimate contact.
  • a flexible force applying means such as a hose adapted to be inflated by a fluid, is disposed in juxtaposition to the outer surfaces of the upstanding leg members of a U-shaped channel. With the reinforcing plate disposed inside the channel at a height medially disposed along the leg members, the flexible force applying means is inflated. As the force applying means inflates, the leg members are urged toward each other and into intimate contact with the two lateral edges of the reinforcing plate.
  • the U-channel When the force applying means is fully inflated and the inner surface of each leg member is in intimate contact with the reinforcing plate, the U-channel is held substantially stationary while the plate is made to undergo linear reciprocating motion in a direction parallel to the longitudinal axis of the U-channel.
  • the peak-to-peak displacement is in the order of one to three mm at a fixed frequency in the range between 100 to 240 Hertz.
  • the present invention provides the advantages of joining thermoplastic parts without the use of solvents, retaining the flash inside the U-channel workpiece, and joining workpieces in a manner to significantly enhance the strength of a U-shaped channel by welding a reinforcing plate to the inner surfaces of the upstanding leg members.
  • a principal object of this invention is the provision of an apparatus for friction welding a reinforcing plate to a substantially U-shaped channel.
  • Another object of the invention is the provision of a friction welding apparatus in which workpieces are urged together in a direction normal to the axis motion but substantially in the plane of the mating surfaces of the workpieces.
  • a further object of the invention is the provision of a welding apparatus employing resilient force applying means for urging the workpieces to be welded into intimate contact.
  • FIG. 1 is a perspective view of a closed U-channel welded in accordance with the prior art
  • FIG. 2 is a perspective view of a reinforced U-channel welded in accordance with the present invention.
  • FIG. 3 is a side elevational view, partly in section, of the welding apparatus with the reinforcing plate in place for welding the reinforcing plate to the inner surfaces of a U-channel;
  • FIG. 4 is a view similar to FIG. 3, but with the resilient force applying means inflated in order to apply engagement pressure between the reinforcing plate and the inner leg surfaces of the U-channel;
  • FIG. 5 is a top plan view for illustrating the means for applying an engagement force between the reinforcing plate and the leg members of the U-channel, and
  • FIG. 6 is a view along line 6--6 in FIG. 5.
  • thermoplastic reinforcing plate 10 to a thermoplastic U-channel 12 having a base portion 14 and two upstanding leg members 16.
  • the rectangular reinforcing plate 10 is joined to the U-channel along the exposed top surfaces 18 of the upstanding leg members 16.
